pfSense® software and the three CVEs announced today

Netgate has performed an assessment of today’s announced vulnerabilities: CVE-2018-8897, CVE-2018-6920, and CVE-2018-6921. We have determined that most users of pfSense® Software have no reason to be concerned. As with Meltdown and Spectre, most pfSense use cases are unaffected, except those with untrusted local users or a multi-tenant context.

screen and tmux

A comparison of the features (or more-so just a table of notes for accessing some of those features) for GNU screen and BSD-licensed tmux.

The formatting here is simple enough to understand (I would hope). ^ means ctrl+, so ^x is ctrl+x. M- means meta (generally left-alt or escape)+, so M-x is left-alt+x

It should be noted that this is no where near a full feature-set of either group. This - being a cheat-sheet - is just to point out the most very basic features to get you on the road.

Trust the developers and manpage writers more than me. This document is originally from 2009 when tmux was still new - since then both of these programs have had many updates and features added (not all of which have been dutifully noted here).
